lectrofishing
is an efficient capture method that can be used to
obtain reliable population estimates, length-weight
relationships, and age and growth on most streams.
Electrofishers tend to collect larger fish more
easily than smaller fish but variable control
electrical transformers allow adjustable control of
voltage, pulse, and electrical frequency thereby
reducing size selectivity. Electrofishing efficiency
can also be affected by stream conductivity,
temperature, depth, and clarity of water. Each
condition must be considered to ensure a reliable
population estimate. Electrofishing can be more
efficient than other methods of population estimates
such as seining and underwater observation.
Boulder-rubble substrate, turbidity, aquatic
vegetation, and undercut banks can bias other
population estimation methods.
Electro-Fishing Unit - Model 2000

Fish Measuring Board
This high density polyethylene Wildco® Fish
Measuring Board provides fast and accurate fish
measurements. Its smooth surface and
east-to-read scales allow for minimal trauma to the
fish during data collection. The tempered
aluminum straight edge is set up for metric
measurements, but can easily be turned around for
English measurements. A tapered backstop helps
prevent fish from sliding off during measurement.
Available in 30" (75cm) and 24" (60 cm) sizes with
English and metric measurements. English scale
has .1" divisions. Metric scale has 1 mm
divisions.
